/* This program generates on Standard Output the XML for an XML-RPC
   call suitable for the xmlrpc_sample_add_server program.

   This is the same XML that the xmlrpc_sample_add_client program sends.

   Use this either as an example of how to use the Xmlrpc-c XML-generating
   functions or to generate XML that you can use to test an XML-RPC
   server.
